Aretha Fiebig

Aretha Fiebig is a Fixed Term Associate Professor at the Department of Microbiology, Genetics, & Immunology within Michigan State University's College of Natural Science. Her research focuses on bacterial environmental sensing and response mechanisms in Alphaproteobacteria.

• Education
  • B.A., Earlham College (1996)
  • M.S., University of Chicago (1999)
  • Ph.D., University of Chicago (2003)

Research Interests:
Dr. Fiebig investigates how Alphaproteobacteria maintain homeostasis through environmental sensing systems. Key areas include:

• Regulation of bacterial surface attachment via holdfast systems
• Molecular mechanisms of general stress response signaling
• Integration of diverse environmental signals in bacterial physiology
• Comparative analysis of sensory protein diversity

Publications Trends:
Her recent work (2015-2025) explores stress response systems, signal transduction mechanisms, and surface attachment regulation in Alphaproteobacteria. The research spans from foundational studies on Caulobacter crescentus to complex systems like Brucella and host-associated bacteria.
